SMOKE-CONSUMER NOZZLE.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed October 31, 1913. Serial No. 798,416.

To all whom it may concern Be it known that I, THOMAS E. McCALL, a citizen of the United States, residing at Wilmington, in the county of Newcastle and State of Delaware, have invented certain new and useful Improvements in Smoke- Consumer Nozzles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a smoke consumer for locomotives and more particularly to the air nozzle which is mounted in the fire-box to supply oxygen to create a more perfect combustion and consumption of the gases. Other devices have been employed for this purpose, but owing to the intense heat, the air nozzles have been destroyed in a short time rendering the device too expensive for use.

The object of the present invention is to provide an air nozzle of such novel form and so mounted as to render it almost proof against the destructive action of the heat.

With these and other objects in view, my invention consists in certain construction and combination of parts as will hereinafter be more fully described and claimed and illustrated in the accompanying drawings, which form a part of this application, and in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my device as shown, that I do not confine myself to the exact design, as slight changes may be made in the construction and combination of the several parts without departing from the spirit of the invention.

In the drawings :Figure 1, is a partial rear view of the fire-box of a locomotive, showing the device installed. Fig. 2, is a sectional view on the line YY of Fig. 1. Fig. 8, is an enlarged longitudinal cross section on the line XX of Fig. 5, of the nozzle showing the same attached to the boiler plates. Fig. 4, is a side elevation of the nozzle removed. Fig. 5, is a view of the same from the inner end. Fig. 6, is a top plan view of the same.

Referring to the drawings, the device comprises a nozzle 3, of steel or other suitable material, oval in cross section and formed near its rear end with a flange 15, for securing it to the outer boiler plate 4. The inner end of the nozzle 3, is contracted as at 7 and is then expanded and bent backward to form an outer wall 8, spaced from the main body to form a chamber 9; the end being flanged at 10, for attachment to the inner boiler plate 5. As a hole 11, is cut in the inner plate 5, to allow the passage of the flange 15, in mounting the device, a communication is formed between the chamber 9, and the water space between the boiler plates, thus allowing a free circulation of water at all times around the end of the nozzle 3, which is exposed to the flame, thus preventing its destruction. The rear end 15, of the nozzle 3, rests against the inner surface of-the outer boiler plate 4, and receives the upper end of the air pipe 2, which is provided with a flanged collar 16, which is riveted to said pipe 2, and secured to the plate 4, and flange 15, by the bolts 17 Said air pipe is supplied with a suitable intake funnel 6, mounted by the side of the engine to receive the air. The usual injector pipes 1, are placedso as to allow room for the air pipe 2.

As the installation and use of this device is well known, further description is deemed unnecessary.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is As an article of manufacture, an air nozzle for smoke consumers, comprising a single casting having a rear flanged end for attachment to the outer wall of a fire-box, a projecting inner end formed with an outer rolled back portion spaced therefrom forming a Water chamber communicating with the water leg of the fire-box, and means for securing said rolled back portion to the inner wall of the fire-box.

In testimony whereof I afiix my signature in presence of two witnesses.

THOMAS E. MoCALL.
